Explanation:
We have,
Ajoba and Prav drive to work. Ajoba drives 45 miles in 2.5 hours. Prav drives 74 km in 1 hour 15 min.
1 mile = 1.6 km
45 miles = 72.42 km
74 miles = 119.0 km
1 hour 15 min means 1.25 hours
Average speed of Ajoba is :
![v_1=\dfrac{72.42 }{2.5}=28.96\ km/h](https://tex.z-dn.net/?f=v_1%3D%5Cdfrac%7B72.42%20%7D%7B2.5%7D%3D28.96%5C%20km%2Fh)
Average speed of Prav,
![v_2=\dfrac{119}{1.25}=95.2\ km/h](https://tex.z-dn.net/?f=v_2%3D%5Cdfrac%7B119%7D%7B1.25%7D%3D95.2%5C%20km%2Fh)
Difference in average speed of Ajoba and Prav is :
![v=v_2-v_1\\\\v=v_2-v_1\\\\v=95.2-28.96\\\\v=66.24\ km/h](https://tex.z-dn.net/?f=v%3Dv_2-v_1%5C%5C%5C%5Cv%3Dv_2-v_1%5C%5C%5C%5Cv%3D95.2-28.96%5C%5C%5C%5Cv%3D66.24%5C%20km%2Fh)
So, the difference in average speed of Ajoba and Prav is 66.24 km/h.
Answer:
The "pressure" of the electricity is electric potential. Electric potential is the amount of energy available to push each unit of charge through an electric circuit. The unit of electric potential is the volt. ... A volt is the force needed to move one amp through a conductor that has 1 ohm of resistance
The ratio of the turns to the voltage should be equal
i.e: 200/120 = t/12
so the secondary coil should have 20 turns
